SPECIFICATION forming part of Letters Patent No. 382,260, dated May 1,1888.

Application filed December 13, 1886. Serial No. 221,360. (No model.)

To all whom it may concern/.-

Be it known that I, FRANK J. HERRIOK, of New Britain, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement Pertaining to Heel-Protectors, of which the following is a description, reference being had to the accompanying drawings, wherein Figure 1 is a view of the bottom of a rubber heel having in it a metallicprotector embodying my said improvement. Fig. 2 is a View of the metallic protector in the same position as shown in Fig. 1, but with the heel omitted. Fig. 3 is a side view of the metallic protector. Fig. 4 is a view of the part shown in Fig. 1 in section on the plane X X.

Thisimprovementpertainstoametallicheelprotector designed andintended to be embodied in a rubber heel in the process oflorrning the heel.

The letter a denotes what I will term friction-studs. Their arrangement with reference to each other is parti-circular. I do not mean to be understood by the use of this term parti-circular that these frictionstuds are necessarily any part of a true circle, but simply that they conform in their arrangement in a general way to the outer rounded surface or periphery of the heel. The faces of thesefriction-studs come to the surface of the heel and there act as heel-protectors. studs a'are united by a bar, I), which is not adapted or designed to come to the surface of the heel, but in the finished heel is sunk below the surface. Being thus sunk below the surface, the connecting-bar b not only greatly assistsin retaining the friction-studs in the heel- These frictionthat is, from dropping out or working out but it also maintains them in their vertical position, each stud being, through the medium of 40 the connecting bar, a help to the others in this respect.

The letter 0 denotes a strengthening-bar.

Rubber heels are formed from a rubber mass in molds under pressure, and this heel-protector is embedded and fastened in the rubber heel during this process of forming the heel.

The preferred mode of making this heelprotector is to cast it in one piece of very hard iron. On the strengthening'bar a there is a spur, d, which I call a mold -rest, because in the mold and when the heel is being formed it rests on one face'of the mold and keeps the whole protector from canting over.

The studs (0 are by preference hollow, and the heelprotector is by preference made of very hard castiron.

I claim as my improvement-- 1. The heel-protector herein described, consisting of a series of studs attached to or connected by a substantially-angular l)l1,lll(1 having a strengtheningbar, 0, provided with a centeringspur or 1nold-rest, d, allsubstantially as described.

2. The within-described hcel-protcctor, consisting of a series of hollow studs attached to or connected by a substantially-angular bar, and having a strengtheningbar, 0, provided with a centering-spur or mold-rest, d, all sub stantially as described.
